A high-accuracy trajectory following controller for pneumatic devices
J. Falcão Carneiro; F. Gomes de AlmeidaThe use of pneumatic devices is widespread among different industrial fields, in tasks like handling or assembly. Pneumatic systems are low-cost, reliable, and compact solutions. However, its use is typically restricted to simple tasks due to the poor performance achieved in applications where accurate motion control is required. This paper presents a novel nonlinear controller, using neural network-based model...
Heat transfer evaluation on industrial pneumatic cylinders
J. F. Carneiro; F. Gomes de AlmeidaAutomatic positioning devices are worldwide used in tasks like handling or assembly, making them key components of modern manufacturing systems. Pneumatic solutions are usually less expensive than their electrical counterparts, are more reliable and require less maintenance. However, the complex nonlinear nature and high model order of pneumatic systems lead to a very difficult control task. These problems mak...
Reduced order thermodynamic models for servopneumatic actuator chambers
J. Falcão Carneiro; F. Gomes de AlmeidaThis paper discusses thermodynamic models of air inside pneumatic actuator chambers. In servopneumatics common practice, these models are simplified by neglecting the temperature dynamics. Classical models in literature assume temperature inside the pneumatic chamber to be either constant or to follow a polytropic law. Furthermore, the mixing process of air entering the chamber and heat transfer between air and...
A contribution to optimal loading/unloading performance in automatic press feed...
J. Falcão Carneiro; A. Pessoa de Magalhães; F. Gomes de Almeida; A. Barata da RochaThis paper presents the MANPRESS robot: a simple, low-cost and newly developed industrial device primarily devoted to press feeding. This robot exhibits two major features: great flexibility to accommodate different machines and products, and optimal performance in loading/unloading one or more machines. The first is due to the usage of modular, off the shelf and easy to control system components. The second is...
